"An interesting patent application recently filed by Microsoft may offer a glimpse at the future of the Windows interface. The patent describes a 'method for managing windows in a display' that seems to describe a method of task switching that is neither Taskbar nor Expose, but something in between." It reminds me of a feature called 'iconify', where you can minimise windows into an icon on the desktop (as CDE has, for instance), a feature I miss in most modern desktop environments.
